' 30 Claims. (Cl. 18541) The invention relates generally to starting devices for internal combustion motors, and particularly to a starting device for a motor of the outboard type.

The general object of the invention is to provide a novel starting device which is simple to operate, which eiectively cranks the motor, and which is inexpensive to manufacture.

It is also an important object to provide a starting device which is so constructed that a backfire of the motor will cause no damage to the parts of the device nor any inconvenience in or disturbance of subsequent operation of the device. l

Another object is to provide a starting device having a rotating member, manually operated for starting and spring returned, which has a, frictional means for connecting the member with the motor and an auxiliary frictional lmeans for insuring disconnection of the member when the motor is started.` 1 y Y A further object is to provide a starting device having a manually operable starting member provided with primary frictional means for Veffecting a driving connection with thej motor, l

for subsequent operation of the device, anovel guide for the rope, and a novel handle for the Tope.

Other objects and advantages Will become apparent from the following description taken in connection with the accompanying drawings, in'

which:

As lheretofore constructed, outboard motors have been provided with a pulley, rigid with the upper end of the motor crank shaft, to receive a rope Wound around the pulley, which is pulled to start the motor. The end, of the rope is adapted to be attached to the pulley by being knotted, with the knot filling in a notch in the pulley. On pulling the rope andV thereby unwinding it from the pulley, the knot is adapted to slip out of the notch so that, should the motor start, the rope will not beA carried around Awith the motor.

Starting devices have been provided for some outboard motors which have the rope permanently attached ,to the pulley and utilize a spring for reversely turning the pulley to wind up the rope after it Ahas been pulled out. Such starting devices use some form of clutch means between the pulley and the crank shaft of the motor. However, unless some provision is made in suchA a starter for backfire, the rope is jerked ing whatever handle may be mountedV on the free end of the rope, and perhaps injuring the operator. 4

If it is desired to disconnect the motor from the starting device when a backfire occurs, Ait

must be kept in `mind that the direction of relative rotation of the parts on backfire is the same as when the crank shaft of the motor is `being turned by the starting device in the operation of starting. Thus one is presented with the problem of Vproviding clutch means which may operate 'at one time and will become inoperable at another with the same relative direction of rotation of'the parts at both times. Partial solution of theproblem hasbeen `madeby providing a releasable connection between 'the starting device as a whole and the fixed parts of the motor, so that on backfire, the entire starting device rotates with the crank shaft in the reverse direction. While this saves damage to the parts of the starting device, it does not prevent the pull rope from being jerked out of the operatcrs hands with the chanceof injury to the operator.

The present invention meets the problem by .providing two connecting or` driving means inter- 'wheel 2l.

posed between the rope and the crank shaft of the motor and both operable for the same relative direction of rotation of the parts. The first of these means is operable under normal circumstances and is adapted to provide a one-way driving connection with the motor crank shaft when the rope is pulled. It thus operates as the primary means for `connecting the pulleyV about which the rope is wrapped. The other means provides normally a driving connection with the motor crank shaft but is releasable when a sud.;- den, excessive torque occurs. The torque, oc.- curring upon the backfire of the motor isV of this character so that said other means releasesthe starting device completely from themotor crank shaft upon occasion of a backfire. Preferably both of these connecting means are of the fric-V tional type.

As shown in the drawings, the outboard motor with which the. starter is illustrated comprises a generally annular fuel tank ,20 within which is.-located the combined ywheelV and magneto 2| mounted on the. motor. crank shaft122.'Y The upper end of. thecrank. shaft' is Aprovidedwith a threaded' portion 23 to which issecuredfa shaft extension, indicated generall'yfat 2li, vandcomprising a hexagonal `portion-.?.5, .a bearingYV portion 26,7and an upper. ythreaded .end 21.. y'I'he starting deviceismounted. on ther shaft extensioni'alll.4

.,A. starting device. embodying thefeainiresA of the. invention Vcomprises generally a, rstniember. adapted to. be manually rotated, andlasecond member normally-connected in driving relationwith a rotating. part of; theY motor such. as thecrank; shaft.. Interposed between. .these two members-is acne-way. driving connection adapt,- ed to bevactuatedwhen the first` member .is manually rotated. The driving connectionalsorincludes means for insuring disengagementthereof. wherrthey motor is started.` Vi/Thile. the Ysecond member is normally connected to the motor `in driving relation,.the connection is such that` upon excessive. torque, Ythe connection is released. Thus. inr case-cf` backfire, the starting device is disconnected from thefmotor, thereby avoiding any damage Yto the device. aswell as avoiding chance of injuryto.- the operator.Y

Inv the present instance, the first member is a pulley 30 (see Fig. v4.) preferably comprising a flat bottomY plate 3'I and an upper platev 32 having its peripheral portion spaced from the bottom plate 3l but having its central portion dished as at 33 to lie inl face-to-face contacting rela-tion with the bottom -plate 3l; Preferably the-two plates are riveted,Y together. The'peripheral portions of the two plates thus forma groove into which is woundY a pull rope` 34 by which the pulley may bel rotated.

The second member inA the present instance is inthe form of' a drum, indicated generally at 35, and comprising' a vertically extending peripheral flange 35 and a bottom 31. The drum. 35 is located adjacent the flywheel. 2l' ofthe motor and has its bottom 3.1 located in. spacedV relationto the end face of theywheel. The: drum is mounted so that it may rotate relative to the ywheelV andi to thisend is provided? with an upwardly and inwardly turned flange itlv fitting around the body of a washerl 4l. The washer 4l isfprovided with a peripheral flangey 42' overlying' the inner flange 45 on the drum to limit the movement of the drum away from the fly- The washer'lll lies against a hub portion of the flywheel 2l and is secured thereto as by a plurality of screws 43. The washer 4I is preferably held against rotation relative to the crank shaft and to this end has a central aperture fitting around the hexagonal portion 25 of the shaft extension 24.

As mentioned above, the invention includes means`v for connecting the Afirst and second members when the first member is rotatedV manually. To this end the pulley 30 is provided with a plurality of downwardly extending pivot pins 44, three in number in the present instance (see Figs. 4, 6 and '7), located eccentric to the axis of the pulley. Mounted on each of the pivot pins 44 is a.shoe,.indicated generally at 45. Each shoe is generally sector shaped with a hub mounted on the pivot pin 44, but the peripheral edge of the shoe is eccentric to its .pivotal axis. Thus, as the. shoe is swung about its peripheral axis, the peripherythereof will move into contact with the inner periphery of the flange 35 of the drum 35. In order to provide a drivingv engagement between the' shoe and the drum, the peripheral edge of the shoe is provided vwith a groove into which ts a strip of leather 4,6, the leather being clamped in place by an arcuate clamping plate il secured to the shoe as by screws 43. Each shoe is preferably. held onvits pivot pin 44 by means'of a split ring 49 (see Fig/4) Vfitting within a groove in the pin. y

The shoes are so arranged thatA when, the pulleyp30 is Yrotated by pulling on the rope 34, centrifugal force or the inertia of the shoes Cause the shoes to swing outwardly from the position shown in Fig. 6k to the position shown in Fig. '7. Thus the leather strips 46 engage and provide a fricticnal driving relation between the pulley and the drum 35. To increase the friction, the inner peripheral surface of the flange 36 of the drum is preferably knurled with vertically extending grooves, as indicated at 5|). A

Another feature of the'invention contemplates the provision of auxiliary'friction Ameans for facilitating engagement of the shoes with thevdrurn when the pulley is manually rotated, and also serving to facilitate disengagement of the shoes from the drum when the motor is started so that the shoes will not drag on the drum. In the preferred' form, such auxiliary means comprises a ii-ber pin 5I mounted in each shoerintermediate the pivotal axis and the periphery thereof and extending downwardly into engagement with the bottom 31 of the drum. Thus when the pulley is manually rotated and before the shoes have moved into contact with the drum, there is relative. movement between the shoes and the drum. However, the pins 5| drag on the .bottom 31 of the drum and cause theshoes to swing into engagement with the drum. When the Inotor has been started, the drag of the ber pins 5I on the drum causes the shoes to swing away from and out of engagement with the drum so that the leatherstrips 46 are completely out-of contactrwith the periphery of the drum. Thus the shoes will not drag on the drum when the motor is operating. In order to limit the swinging movement of the shoes in both directions, lugs 54 are punched from the bottom plate 31 of the pulley and are bent downwardly into the path of the shoes.

The structure thus far described is utilized during normal starting operations. However, as mentioned above, the invention includes a provision 'to avoid damage when the motor backres. Generally such provision comprisesa sec- `ondary friction means or-driving connection beden excessive torque such as occurs upon backnre. In the present instance the connection between the drum and the flywheel is frictional. As shown herein, the connection comprises a resilient dished ring 52 locatedin the space between the bottom 31 of the drum and the flywheel 2|,` and holding the inner flange 40 of the drum in contact with the peripheral flange 42 of the washer 4|. In the preferred arrangement, the innerrmarginal portion of the disk 52 bears against the bottom 31 of the drum, while the outer marginal portion bears against the fly wheel 2|. In order to provide a suitable bearing surface on the ywheel 2|, a low rib 53 may be formed thereon.

The resilient ring`52 is shapedso that when it is free it has a greater height than is shown in Fig. 4, but when assembled and the screws 43 which hold the washer 4| in place are tightened, the height of the ring 52 is decreased to place it under tension. The ring thus on its marginal i portions frictionally engages the drum and the flywheel suiciently to provide a driving connection therebetween. However, should there be a sudden excessive torque such as occurs when the engine backres, the drum and flywheel will slip` relative to each other, thus in effect Vdisconnecting the starting device from the iiywheel.

As mentioned above, the pulley is rotatably mounted on the lbearing portion 26 of theshaft extension 24. with a hub 60 seated on a washer 6| on the shaft extension, and roller bearings 62 are provided between the hub 60 and the bearing portion 26. In order to provide for lubrication of the roller bearing 62, a central -bore 63 is made in the shaft extension 24 and a transverse bore 64 extends therefrom to the bearing.

To secure the inner end of the rope permanently to the pulley, an aperture 65 is punched in the lower plate 3| of the pulley and `a down-iH wardly dished lip 66 is formed in the bottom plate so that the rope may extend through the bottom plate without having to pass over a sharp edge of metal. The end of the rope is bent into a generally square loop 61, as shown in Fig.` 5, lying against the bottom face of the lower plate 3| and is clamped in place by a clamp comprising Ya flat central portion secured to the -bottom plate by a screw 1|. At each end of the flat bottom portion 10 are U-shaped portions 12 t- Y ting over and clamping the rope in place.

The rope is wrapped around the pulley sufficiently so that each time the rope is pulled, the motor crank shaft is turned over approximately two and one-half times, which is found to be sufficient for starting. v r

The invention also includes means for automatically rewinding the rope 'on the' pulley. `Said I means in the present instance comprises acover plate 13 (see Figs. 4 and 8) havinga downwardly extendingV peripheral flange V14 enclosing the pulley 30. At one side, the ilange 14 is 4provided with an aperture '|5thrcugh which the rope 34 extends tangentially.- Under'the cover plate 13 is a `torsion spring 16 comprising a flat strip of resilient metal wound in a loose spiral. The torsion spring 16 isconnected at oneof its ends to the cover plate 13 and at its'other end to the pulley so as to rotate the pulley in a. directionto wind the rope thereon. To thisend,`

To this end the pulley is provided i' the inner end `of the torsion spring 16 is formed into a curl 11 adapted to t into and be retained by a notch 18 formed in the periphery of the hub 60 of the pulley. The outer end of the spring is bent into a loop 80 and secured over a downwardly i extending pin 8|? rigid with the cover plate 13. The spring 16 extends partially into the dished portion 33 of the pulley 3| and is confined by a plurality of annularly arranged an auxiliary pulley "tion so that the outer end of the spring is thereby anchored. For holding the cover plate against rotation, a pair of L-shaped lugs 83 are pro- -`vided. Each lug has one leg secured to the outer Vperiphery of the flange 14 of the cover plate and the other leg projecting radially therefrom in abutment with the adjacent lug. Secured to the inner peripheral face of the tank 20 (see Figs. 1 and 2) is a pair of generally similar L-shaped lugs 84. The lugs 84 are mounted in spaced relation to each other so that the lugs 83 may extend therebtween. To cushion the starter and to prevent rattle between the lugs, a tubular rubber bushing 85 may be slipped over the lugs 83. i Another feature of the invention resides ln the manner in which the outer or free end of the rope is held in a convenient location soV that the operator may readily grasp it to start the motor. To this end, a tube extends through the gasoline tank to provide a guide for the rope, and in the outer end of the tube is mounted a bushing 9| having a hole therethrough of sufficient size to permit the passage of the rope. The outer end of the bushing 9| is provided with a collar 02, and a rubber grommet 93 extends from the collar rearwardly against the tank to provide a neat appearance. v

The outer end of the rope is provided with a handle preferably made of rubber.` The handle in its preferred form comprises a shank portion 94 having a pair of laterally projecting portions 95 shaped to be readily grasped in the hand. The shank is hollow and internally is provided with a steel cup or thimble 96. The bottom of the cup 96 is provided with an aperture through which the rope extends and the end of the rope is knotted with the knot seated in the cup. Thus the handle is rigidly secured to the rope. The outer end of the hollow shank is adapted to be closed by a rubber plug 91 having inwardly tapered sides `fitting a correspondingly shaped portion on the interior of the shank and thereby removably retained within the shank. In order to hold the handle in the same position each time the rope is wound up by the spring, the inner end of the shank of the handle is provided with a pair of diametrically spaced V- shaped lugs 98 adapted to be received by correspondingly Vshaped notches in the collar 92.

The starting device may also be provided with |00 secured to the shaft extensionl and adapted to be used with a rope having a knot fitting into a notch |0| in the flange of the pulley. For securing the pulley to the shaft extension, a washer |02 is mounted onthe threaded end portion 21 of the shaft extension and a nut on Vthe threaded portion clamps the pulley |00 against the washer |02.

`In operation of the device, .the operator grasps `be manually turned, each of said shoes also having an auxiliary frietionalmeans in engagement with the member connected to the'motor'and -positioned relative tothe pivotal axis ofthe shoe to cause the shoe to swing out of engagement with said member when the motor rotates Afaster than the manually rotatable member. j
